Question: A thin 3 3 c m 2 5 c m flat plate is pulled at 3 . 2 m s ( V in figure below

A thin 33cm25cm flat plate is pulled at 3.2ms(V in figure below) horizontally through a
3.6-mm-thick oil layer sandwiched between two plates, one stationary and the other moving
at a constant velocity of 0.27ms(Vw in figure below), as shown below. The dynamic viscosity
of the oil is 0.012Pa*s. Assuming the velocity in each oil layer to vary linearly, determine the
force in Newton that needs to be applied on the plate to maintain this motion.
